From what I hear it's turning fairly intelligent to asshole
99% of people within FAANG are the most friendly people ever. E.g. for Google not being a dick is a hiring criteria (Googleyness).
I worked at one the FAANG and I found in my team and some of the neighboring teams the most insecure, unfriendly, back-stabbing, conspiratorial bunch of technically semi-competent losers I ever had the displeasure of working with. Other people were competent, trustworthy, confident in themselves and thus enjoyable.
I also interviewed at other FAANGs and maybe the interviewers were all wonderful people, but I had a mixed experience. Some appeared to be ok, some definitely not. Very different experience from the parent's.
